Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding device of a camera for feeding a film with a magnetic storage unit when writing information to the magnetic storage unit of the film.

[0002]

2. Description of the Related Art Conventionally, for example, according to Japanese Patent Application Laid-Open No. 2-67534, a film spool is rotated in order to rotate the film spool in the cartridge so as to feed the film from the cartridge and wind the film on a take-up spool. A method is described in which the reduction gear ratio of the returning gear train is set to be larger than that of the film winding gear train.

Further, according to Japanese Patent Laid-Open No. 4-128732, the output when the roller member is positioned on the film surface during film feeding is supplied as a signal for instructing recording of information, and the roller member A method is described in which magnetic information is written on a film by supplying an output when the film is located at the perforation of the film as a signal for frame positioning. Then, these methods have been combined to try to accurately write magnetic information in the magnetic storage portion of the film.

[0004]

However, when magnetic information is written on a film using the above method,
In particular, there is a case in which the running of the film, that is, the running amount and the running speed become uneven between the shooting start frame and the initial shooting frame when the film is loaded, and normal magnetic information writing may not be performed.

It is considered that this is because the films wound on the take-up spool relatively move while the film is being turned. FIG. 6 is a diagram showing this phenomenon,
The upper graph 100 shows the current flowing through the film winding motor, and the lower graph 102 is the pulse indicating the film running. In the graph 102 showing the running of the film, there are many portions where the pulse width is not uniform. This indicates that the film is not running uniformly.

Therefore, the present invention has been made to solve the above-mentioned problems, and the film can be run by surely winding the film around the film winding shaft without slack and by securely winding the films together. An object of the present invention is to provide a film feeding device for a camera that can uniformly perform magnetic recording reliably.

[0007]

In order to achieve the above object, the film feeding device for a camera of the present invention uses a cartridge having a film with a magnetic storage section contained therein.
A camera provided with a magnetic head for sending out a film from the cartridge, and writing information to the magnetic storage portion of the film while winding the film on a film take-up spool, and a driving means for moving the film. Receiving the driving force of the driving means, winding the film, and receiving the driving force in the opposite direction of the driving force, the winding means not receiving the driving force and the driving force of the driving means. Then, in order to feed the film from the cartridge and further feed the film to the winding means, the feeding means having a speed slower than the winding speed of the film by the winding means and the cartridge to the camera. After loading the film by a specified number of frames after loading it, the cart is moved by the number smaller than the specified number of frames. Characterized by comprising a control means for rewinding the film into Tsu the di.

Further, in the film feeding apparatus of the camera of the present invention, after the control means executes the rewinding operation of rewinding the film into the cartridge by the number of frames smaller than the predetermined number of frames, Further, it is characterized in that the film is wound up and set as the first frame of photographing.

Further, the film feeding device of the camera of the present invention is a camera in which a film having a magnetic recording portion is contained and a cartridge having a function of sending out the film can be loaded, and a detection for detecting loading of the cartridge is detected. Means, an idle feed means for performing the idle feed operation of the film by a predetermined number of frames larger than the idle feed frame number according to the loading of the cartridge by the detection means, and after the idle feed operation by the idle feed means is completed, Rewinding means for performing a rewinding operation for the number of frames smaller than the predetermined number of frames up to the position of the first frame for photographing the film are provided.

That is, in the film feeding device for the camera, when the forward driving force of the driving means is received, the film is wound by the winding means, but the driving force of the driving means in the reverse direction is applied. When I received it,
This driving force is not transmitted to the winding shaft by the winding means. Further, in order to feed the film from the cartridge in response to the driving force of the driving means and feed the film to the winding means side, the feeding speed is higher than the speed at which the winding means winds the film. Will be slowed down. Then, after the cartridge is loaded in the camera, the film is fed by a predetermined number of frames by the control means, and then the film is rewound into the cartridge by a number smaller than the predetermined number of frames.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a perspective view showing the mechanical structure of the film feeding device of the camera according to the embodiment of the present invention.

The mechanical structure for feeding the film in the film feeding device of this camera is the same as that disclosed in the above-mentioned Japanese Patent Laid-Open No. 2-67534.
That is, the feeding device of this camera has a film feeding motor 14 as a single driving source for driving the film winding shaft (winding spool) 10 and the rewinding shaft 12, and further, the film feeding motor. Motor 14 and winding shaft 10
And a gear train 18 that connects the film feeding motor 14 and the rewinding shaft 12. The former gear train 16 has a lower gear ratio than the latter gear train 18, and the film winding speed by the winding shaft 10 is
It is set to be faster than the delivery speed delivered from the cartridge by the rewind shaft 12.

A one-way clutch 16a is present in the gear train 16, and the one-way clutch 16a is used for winding the film when the film feeding motor 1 is used.
4 is transmitted to the take-up shaft 10, otherwise the drive force of the film feed motor 14 is not transmitted to the take-up shaft 10 when the film moves away from the take-up shaft 10. Work on.

The gear train 18 has a sun gear 18 in the middle thereof.
a and a planetary lever 18c composed of a planetary gear 18b. The sun gear 18a meshing with the planet gear 18b
The driving force of the film feed motor 14 is transmitted to the motor. Driven gear 2 driven by planetary gear 18b
Two 0 and 22 are provided in front of the planetary gear 18b depending on the rotation direction of the film feeding motor 14.
Is engaged with the driven gears 20 and 22.

On the other hand, the driven gear 20 drives a fork member 26 as the rewinding shaft 12 via a one-way clutch 24. When the driving force of the film feed motor 14 for feeding the film from the cartridge is transmitted to the driven gear 20, the one-way clutch 24 connects the driven gear 20 and the fork member 26, and feeds the film from the cartridge. However, when the film is pulled out of the cartridge at a speed higher than the feeding speed, the connection of the one-way clutch 24 is disconnected,
This pulling force is not transmitted to the driven gear 20.

The other driven gear 22 is connected to the fork member 26 via another gear train 28. This transmission mechanism functions when the driving force of the film feed motor 14 for rewinding is transmitted to the planetary gear 18b.

Next, a description will be given of the operations of the film feeding in the film feeding device of the camera constructed as described above, such as the idling of the film and the winding and rewinding during the normal photographing. When the film feeding motor 14 is rotated in one direction for feeding the film, this rotation drives the gear train 16,
The winding shaft 10 is driven. At the same time, the gear train 18 is also driven, the planetary gear 18b meshes with the driven gear 20, and the fork member 26 is rotated via the rewind shaft 12 to feed the film.

When the film is sent out and taken up by the take-up shaft 10, the take-up speed of the take-up shaft 10 is faster than the take-out speed of the rewind shaft 12, so that the driven gear 20 and the fork member 26 are separated from each other. In the meantime, the one-way clutch 24 is disconnected,
Only the fork member 26 rotates. Even when winding up after normal photographing, the fork member 26 rotates by the same operation.

At the time of rewinding, the film feeding motor 14 is rotated in the direction opposite to the above-described winding and winding. Then, the driving force transmitted to the driven gear 16b does not rotate the winding shaft 10 because the driven gear 16b and the winding shaft 10 are disconnected from each other by the one-way clutch 16a. On the other hand, when the film feeding motor 14 rotates in the direction opposite to that at the time of winding, the planet gear 18b and the driven gear 22 mesh with each other. Thus, the driving force transmitted from the film feed motor 14 to the planet gears 18 b of the gear train 18 is transmitted to the driven gear 22, and further causes the fork member 26 to rewind in the rewind direction via the gear train 28. Rotate to. Then, the film is rewound by the rotation of the fork member 26.

FIG. 1 is a block diagram showing a circuit configuration of a camera to which this film feeding device is applied. An operation control unit (hereinafter referred to as CPU) 30 is the center of operation control in this camera, and various circuits and mechanisms for performing camera operation are connected and arranged around the CPU 30. Then, it operates according to the instruction of the CPU 30 or C
It provides information to the PU 30.

The distance measuring circuit 32 is for measuring the distance to the subject, and the measured distance information of the subject is stored in the CPU 3
Input to the CPU 30 via the input port I4 of 0. The photometric circuit 34 measures the luminance of the subject, and the measured luminance information of the subject is input to the input port I5 of the CPU 30.
Input to the CPU 30 via.

The CPU 30 controls the shutter / aperture control circuit 36 to execute the exposure operation according to the inputted brightness information, and controls the focus adjustment circuit 38 to execute the focus adjustment operation according to the distance information. To do. In this focus adjustment operation, when the photographer half-presses the release button, the CPU 30 detects via the input port I1 that the first release switch (1st. If executed. Also,
In the exposure operation, when the photographer fully presses the release button, the second release switch (2nd. Release SW) 42 that is turned on in synchronization with this is turned on.
It is executed when U30 detects it through the input port I2.

Further, the storage chamber lid switch (SW) 44
Is a switch that is turned on when the film cartridge 46 is loaded in the accommodation chamber of the camera body and the lid of the accommodation chamber is closed. When the CPU 30 detects that the switch is turned on through the input port I3. The feeding operation of the film 48 is started.

The film 48 wound in the film cartridge 46 is sent out of the film cartridge 46 by rotating a spool shaft (not shown) in the film cartridge 46. This feeding operation is performed by the film feeding motor 14 and the gear train 18 for rotating the spool shaft by the driving force.
The driving is performed by a driven mechanism including the driven gear 20, the fork member 26, and the like. The driving force of the film feed motor 14 is also transmitted to the take-up spool 10 at the same time.
When the fed film 48 reaches the take-up spool 10, the film 48 is taken up by the take-up spool 10.

Further, the peripheral speed V1 at which the film 48 is sent out from the film cartridge 46 and the peripheral speed V2 when the film 48 is wound by the take-up spool 10 are normally set to V1 <V2. After the film 48 is wound on the take-up spool 10, the film 48 is fed by the take-up spool 10. The film feeding motor 14 is driven by a motor drive circuit 50, and the CPU 30 is driven through an output port O3 of the CPU 30.
Is controlled by

The film cartridge 46 is provided with a disc 52 which is interlocked with the rotation of the spool shaft in the film cartridge 46, and a bar code 54 is printed on the disc 52. The bar code 54 encodes information relating to the characteristics of the film 48 and the film cartridge 46. By discriminating the bar code 54, the film sensitivity information, the number of photographed frames information,
You can get negative / positive information. Also, depending on the initial position, it is possible to detect the exposure state of the film 48, that is, whether or not the built-in film has already been exposed.

The information recorded on the bar code 54 is read out by the photo sensor 56 while rotating the disc 52 fixed to the spool shaft in the direction opposite to the feeding direction of the film 48. . The photo sensor 56 is a photo reflector that emits light onto the disk 52 and receives the reflected light, and detects a change in the amount of reflected light caused by the presence or absence of the bar code 54. The bar code detection circuit 58 converts the analog output of the photo sensor 56 into a digital pulse, and inputs it to the input port I of the CPU 30.
It inputs to CPU30 via 7. The CPU 30 decodes this digital pulse to determine the above information.

Further, the mechanism for detecting the feeding state of the film 48 is a driven roller 6 which is driven by the film 48 to rotate.
0, and an encoder plate 62 that interlocks with the driven roller 60
And a photo sensor 64 for detecting a slit provided on the encoder plate 62, and a feeding state detection circuit 66 for converting the analog output of the photo sensor 64 into digital pulses. Then, the CPU 30 uses the input port I6
The feeding amount of the film 48 is detected by receiving the digital pulse from the feeding state detecting circuit 66 via the, and counting the number.

Further, the film 48 has a magnetic recording portion (not shown) extending in the longitudinal direction thereof so that photographing information and the like can be recorded. This recording is performed as follows. The CPU 30 supplies a magnetic recording signal to the magnetic head drive circuit 68 via the output port O4 in synchronism with the digital pulse for detecting the film feeding state input via the input port I6. And
The magnetic head drive circuit 68 receives the magnetic recording signal and drives the magnetic head 70 to record magnetic information in the magnetic recording section.

Next, the processing of the CPU 30 as the operation of the feeding device of this camera will be described with reference to the flow chart shown in FIG. When the CPU 30 detects that the storage chamber lid SW44 is turned on, the main routine (not shown)
To enter this "autoload" routine.

First, the CPU 30 reversely drives the film feeding motor (M) 14 to rotate the spool shaft in the film cartridge 46 in the direction opposite to the film feeding direction, and the photo sensor 56 and the bar code detecting circuit 58. The information recorded in the bar code is read using (step S1).

Here, the CPU 30 determines whether or not the initial position of the bar code is at the position indicating the unexposed state (step S2). If it is not unexposed, it warns that it has already been exposed (step S9) and returns to the main routine. On the other hand, when it is not exposed, the motor drive circuit 50 is instructed to rotate the film feeding motor 14 in the normal direction (step S3).

Next, the CPU 30 monitors the feeding amount of the film 48 from the pulse signal input to the input port I6 via the driven roller 60, the encoder plate 62, the photo sensor 64, and the feeding state detection circuit 66. . When the nth frame of the film 48 is fed to the exposure position, the film feeding motor 14 is once stopped (steps S4 and S5). Subsequently, the film feeding motor 14 is rotated in the reverse direction to load the film 48 into the film cartridge 46.
It is rewound inside (step S6).

Then, the CPU 30 monitors the feeding amount of the film 48 from the pulse signal input to the input port I6, and judges whether the first frame of the film 48 has returned to the exposure position (step S7), 1 When the frame returns to the exposure position, the film feeding motor 14 is stopped (step S8). After that, this routine is terminated and returns to the main routine.

The number n of frames wound in step S4 is the number of frames required for the film 48 to be tightly wound around the take-up spool 10, and is a value to be determined by experiment. Whether the nth frame and the first frame of the film 48 have been fed to the exposure position in steps S4 and S7 is determined by the driven roller 60, the encoder plate 62,
Although the pulse signal output from the photo sensor 64 and the feeding state detection circuit 66 is used, the determination may be made by detecting the position of the perforation provided on the film 48. Further, in the flow chart shown in FIG. 3, after feeding the nth frame to the exposure position and stopping the film feeding motor 14, the film feeding motor 14 is rotated in the reverse direction to move the first frame to the exposure position. However, when the nth frame is fed to the exposure position without returning the first frame to the exposure position, the process may return to the main routine to record and reproduce the magnetic information.

Next, referring to the flow chart shown in FIG. 4, the CPU 3 as a modified example of the operation of the feeding device of this camera.
The process of 0 will be described. This modified example is an example in which the operation is controlled based on the number-of-photographed frames information in the information recorded in the barcode 54.

The processes of steps S1, S2 and S9 are the same as the processes in the flowchart shown in FIG. When the photographic frame has not been exposed in step S2, the CPU 30 determines whether the film cartridge 46 has a small number of photographic frames (step S10). When the film cartridge 46 having a small number of frames to be photographed is loaded, the n-th frame is once fed (steps S3, S4, S5) and then the first frame is wound, as in the process of the flowchart shown in FIG. Return (steps S6, S7, S8). Then, this routine is finished and returns to the main routine.

On the other hand, when the film cartridge 46 having a small number of frames is loaded in step S10, the CPU 30 rotates the film feeding motor 14 in the normal direction (step S11), and then feeds the film 48. The amount is monitored, and when the first frame is fed to the exposure position, the film feeding motor 14 is stopped (steps S12 and S1).
3). After that, this routine is terminated and returns to the main routine.

Such operation control is performed because a film cartridge having a smaller number of frames causes more uneven running of the film, and the magnetic information cannot be normally written. Is. As a result, unless the film cartridge has a small number of frames, the operating time for film feeding and winding can be shortened.

The number n of frames wound in step S4 is the number of frames required for the film 48 to be tightly wound around the take-up spool 10, and is a value to be determined by experiment. Whether the nth frame and the first frame of the film 48 have been fed to the exposure position in steps S4 and S7 is determined by the driven roller 60, the encoder plate 62,
Although the pulse signal output from the photo sensor 64 and the feeding state detection circuit 66 is used, the determination may be made by detecting the position of the perforation provided on the film 48. Further, in the flow chart shown in FIG. 4, after feeding the n-th frame to the exposure position and stopping the film feeding motor 14, the film feeding motor 14 is rotated in the reverse direction so that the first frame is exposed to the exposure position. However, when the nth frame is fed to the exposure position without returning the first frame to the exposure position, the process may return to the main routine to record and reproduce the magnetic information.

Next, referring to the flowchart shown in FIG. 5, a CP as another modification of the operation of the feeding device of this camera.
The processing of U30 will be described. The processing of steps S1 to S6 and step S9 is the same as the processing in the flowchart shown in FIG. After winding up to the nth frame, the film feeding motor 14 is reversed in step S6 to rewind the film 48 into the film cartridge 46 (step S6).
0 monitors the feeding amount of the film 48, and judges whether the -1st frame has been rewound to the exposure position (step S).
101). Then, when the -1st frame is rewound to the exposure position, the film feeding motor 14 is stopped (step S102).

Subsequently, the CPU 30 waits for 100 ms (step S103), and then the film feeding motor 1 again.
4 in the normal direction (step S104), and 1 of the film 48
It is determined whether or not the frame has been fed to the exposure position (step S7). When the first frame is fed to the exposure position, the film feeding motor 14 is stopped (step S8). After that, this routine is terminated and returns to the main routine.

That is, in the operation control shown in FIGS. 3 and 4, after winding up to the nth frame, the first frame is rewound so as to be located at the photographing position. Rewind from the first frame to the -1st frame as shown in 100
After waiting for ms, the first frame may be wound up again. Thereby, the film can be more reliably wound around the take-up spool.

Incidentally, the above steps S101 to S10.
The processes up to 4 can be applied to the flowcharts shown in FIGS. 3 and 4. As for the number n of frames to be wound up in step S4, the film 48 is wound on the spool 1
It is the number of frames required to tightly wrap around 0, and is a value that should be determined by experiment. Whether the nth frame and the first frame of the film 48 have been fed to the exposure position in steps S4 and S7 is determined by the driven roller 60, the encoder plate 62, the photosensor 64, and the feeding state detection circuit 6.
Although it is performed by the pulse signal output via 6, it may be determined by detecting the position of perforation provided on the film 48. Further, in the flow chart shown in FIG. 5, after feeding the n-th frame to the exposure position and stopping the film feeding motor 14, the film feeding motor 14 is rotated in the reverse direction so that the first frame is exposed. Back up to
It is also possible to return to the main routine to record and reproduce magnetic information when the nth frame is fed to the exposure position without returning the first frame to the exposure position.

As described above, according to the above-described embodiment, the film once wound is rewound into the film cartridge, and the film is firmly wound on the film winding shaft, that is, the film winding shaft and the film winding shaft are wound.
